Hands down one of the most useful purchases I’ve made for my kid. My daughter was able to wear this for 3 years from age 3.5-6.5. Only flaw is slightly dingy on lower inside legs. Your kid can throw this on over their clothes with boots and literally splash their heart out and sit in puddles all while staying perfectly dry. A must have. Size 104/4 perfect size for 3-6 year olds.
